Initially I cross flashed my K530i to W660i firmware and managed to unlock the simlock. I did this by following firstly this video and then the walkthrough:
YouTube - Howto flash k530i with CID 53 to w660i
SE-NSE Forums > [cid53] W660 Ultimate Guide!
Now I decided to flash the phone back to generic K530i firmware:
MAIN_K530_R8BB001_MAIN_GENERIC_NC_RED53.mbn
FS_K530_R8BB001_FS_EUROPE_3_RED53.fbn
K530_HB1-06_Gen_CDA102568_2_R8A_GENERIC_CENT_EUROPE
This all went through no problem.
Then I tried to follow the second section of
SE-NSE Forums > [cid53] W660 Ultimate Guide! so I could unlock the phone with W530i firmware. This is where things went wrong.
The BREAK copied OK, so did the FS and the BFILES (look at walkthrough first).
After flashing I turned the phone on and it started loading and hung on "please wait" for ever. I took the battery out and put it back in turned it on and nothing. Just a black screen. Now when I try to flash new firmware on to it I get an error.
The MAIN copies OK but the FS stops at part 138 and then I get an error.
Is the phone dead?
